What is the output of the IC 7924?

What is the output of the IC 7924? Correct Answer -24V

The IC of series 78xx and 79xx are fixed voltage regulators, wherein the 78 represents those with a positive output and 79 is for those with a negative output. The xx value represents the magnitude of the output voltage being achieved. For proper operation, the input voltage should be at least 2V greater than the output voltage.
